Specification forming part of Letters Patent No. Aaiflfili, dated November 272, 1864.

To all whom it may concern the pan A, and the holes b connect with the Be it known that we, F. MOREAU and F. holes a by means of pipes c, as shown clearly ROBERT, of No. 57 Cedar street, in the city, in Fig. 1 of the drawings, each alternate hole county, and State of New Yorlnhave invented in the bottom of the pan A being connected a new and Improved Apparatus for Marbling to one of the holes b in the bottom of the pan Soap; and we do hereby declare that the fol- B. lowing is a full, clear, and exact description 0 is a plate, of sheet metal, which is perfothereof, which will enable others skilled in rated with a series of holes equal in number, the art to make and use the same, reference size, and position to the pipes 0, and said plate being had to the accompanying drawings, is made to fit nicely in the pan A and over the forming part of this specification, in whichpipes c, as shown in the drawings. A handle, Figure l is a longitudinal vertical section D, serves to raise and lower the same. A of this invention, the line 00 00, Fig. 2, indicatsimilar plate, I but not perforated, is fitted l ing the plane of section. Fig. 2 is a horizontal into the upper pan, B, and a handle, F, serves section of the same taken in the plane indito raise and depress this plate. A suitable cated by the line y y, Fig. 1. Fig. 3 is a parslide must be applied to close the holes and tial inverted plan of the same in proper scale orifices in the bottom of the pan A.

or proportion. The operation is as follows: The soap paste Similar letters of reference indicate like is divided in two parts, one containing twoparts. fifths ({:j-) and the other three-fifths (i of the This invention relates to an apparatus for whole mass. The latter partis converted into marbling soap which is composed of two pans a blue soap by means of ferrocyanide of alumof sheet metal or other suitable material, iuum or any other suitable pigment! After I one placed under the other. The bottom of the blue soap has been prepared it is poured the lower pan is perforated with a large num' in the lower pan, A, and the white soap is her of holes placed as close together as posplaced .in the upper pan, B. The slide or gate, sible, and from onesixteenth to two sixclosing the holes a, is opened and a certain teenths of an inch in diameter. The bot pressure is exerted on both plates 0 and E. tom of the upper pan is also perforated with The paste, which is yet in a semi-liquid state,

one-half as many holes as that in the bottom discharges in a suitable reservoir under the of the lower pan, and the holes in the upper panA, and a perfect mixture of white and pan are connected to those in the lower pan blue soap is obtained, equal in every respect by pipes of copper or other suitable material to the soap of Marseilles. In this state the perfectly smooth and round in such a manner mixture has not yet passed into the state of that the contents of the upper pan when disacid fat, and, in order to effect this purpose,it i charging pass through those of the lower pan is only necessary to expose the same for about without mixing with the same. A plate of six (6) days (more or less) to the influence of metal or other suitable material which is fitted the atmospheric air. During that time the over the pipes in the lower pan serves to exiron in the ferrocyanide is brought to its minert a pressure, whereby the discharge of the imum of oxidation, and the blue color of the paste is facilitated, and a similar plate, which, soap turns red precisely like the soap of Marhowever, is not perforated, serves to exert a seilles. After the soap thus prepared has pressure on the contents of the upper pan. been poured in the mold it is left to stand The holes and orifices of the pipes in the botuntil it assumes the proper consistency to be tom of the lower pan have to be closed by a cut in cu ical blocks, which takes place after suitable slide. a lapse of twenty-four (24) hours. After hav- A represents the lower pan, the bottom of ing been cut the soap is soaked, which is which is perforated with a series of holes, a. effected by placing it for four (4) or five (5) B is the upper pan, equal in size and shape days in a vessel containing a lye brought to a to the pan A, or nearly so, and having its botstrength of eight- (8) degrees by a solution of tom perforatedwitha series ofholes, Z), equalin chloride of sodium and afterward ten (10) number to one-half that of the holes in the botdegrees by a solution of oxide of sodium.
